Emulsions are a thermodynamically unstable heterogeneous system consisting of a bitumen phase and aqueous phase formed by water, emulsifiers and pH-regulating agents. This natural instability gives rise to a natural process called sedimentation that causes the separation of the water and bitumen phases. This can lead to the total or partial fracture of the emulsion, going from a typical sedimentation process to flocculation and coalescence.
The applications of our Export range of emulsions include priming coating, adherence and curing, bituminous slurries and cold microsurfacing, emulsion gravel, superficial treatments by means of gravel coating, open-graded bituminous mixtures and cooled mixtures manufactured by emulsion.
The Export range of emulsions therefore offers the following advantages:
